Easily assign custom, widget-enabled sidebars to any page.
If your page has any custom loops or queries, they need to be followed by
wp_reset_query(), otherwise the global
$post variable will no longer reference the correct post and by the time the sidebar is displayed, Simple Page Sidebars won't know which page is being viewed, possibly leading to an unexpected sidebar being displayed.
Some themes register different sidebars for their page templates, which means there isn't a default sidebar that can be replaced. To use Simple Page Sidebars in this instance, you can create a child theme and force page templates with custom sidebars to use the default sidebar.
